For currency conversion, use XE for reliable live rates and offline conversions; for city transit, choose Citymapper; for broad international transit and offline maps, use Google Maps; use Revolut or Wise for low-fee spending and transfers; use Rome2rio for long-distance, multi-modal planning.
1XEXE is best when you need trustworthy live exchange rates plus offline conversion—tracks many currencies and offers alerts, making it ideal for travelers who need accurate checks without data.88%
2CitymapperCitymapper is the best fit for navigating complex urban transit—offers highly detailed, real-time step-by-step routes, schedules and even carriage-level tips, but it’s strongest in major cities only.85%
If you’re traveling internationally, I’d use one currency app + one transit app, rather than trying to make one app do everything.
💱 Best currency apps
XE Currency — best overall for travelers. Great for quick conversions, rate tracking, alerts, and offline use.
Wise — best when you’re actually exchanging or sending money. It’s particularly useful for comparing the rate you’ll receive against the mid-market rate and understanding fees.
— good options if you only need quick price conversions.
Currency Converter Plus / My Currency Converter & Rates
simple, offline
My pick: XE for checking prices; Wise if you also need to move money.
🚇 Best public-transit apps
Google Maps — best default for most travelers. It combines walking, buses, trains, metro, and places in one app, and offline maps are particularly useful abroad.
Citymapper — best for major cities with complex transit systems. It provides detailed multimodal routing, live departures, stop alerts, and station/route guidance. Coverage is the key limitation, so check whether your destination is supported.
Moovit — best backup for international travel and less-obvious cities. Its broad coverage of buses, trains, ferries and other transit can be particularly useful when Citymapper isn't available.
Transit — excellent for real-time urban transit, particularly in North America; its strength is quickly seeing nearby vehicles and live arrival information.

Best minimalist setup:XE + Google Maps + Citymapper (when your destination is supported). Download your maps/routes before leaving Wi-Fi, and check the local transit authority's app for major service disruptions when available.
If I'm standing at a busy counter in a train station or a market, I don't want to unlock my phone, find the calculator, swipe to the conversion tool, and type.
Google for quick checks while moving - no app to open, works offline if you've visited the page recently, and the calculator is right there.
Best Public Transit Navigation Apps
Citymapper — The gold standard for urban transit. If you are visiting a supported major global metropolis (like London, New York, Tokyo, or Paris), Citymapper combines every mode of transit—subway, bus, ferry, bike share, and walking—with hyper-accurate real-time updates. It even tells you which train car or exit to use so you surface closest to your destination.[](https://www.pcmag.com/picks/the-best-navigation-apps)
Google Maps — The most reliable universal backup. While it doesn't get as granular as Citymapper on specific metro car exits, its public transit routing handles multi-leg journeys globally. Crucially, you can download offline map grids ahead of time.[](https://www.pcmag.com/picks/the-best-navigation-apps)
Official Local Transit Apps — For specific regions, third-party apps can miss local quirks. Always check if the city has a dedicated official app (e.g., in New York, or in Germany) for the most accurate service change alerts and localized ticketing integration.
If you tell me which country or cities you are visiting next, I can recommend local apps, transit pass tips, or specific offline strategies tailored to your itinerary.
For most travelers, a small set of apps covers currency conversion and public transit well. The best choices depend on whether you need quick price checks, international spending, or detailed city navigation.
Currency conversion apps
XE — Best general-purpose converter
Live exchange rates, many currencies, rate alerts, and offline cached rates.
Great for quickly checking “How much is this in dollars/euros/etc.?” while shopping or eating abroad.
Wise — Best for actually spending money abroad
Useful if you want to hold multiple currencies and pay with a linked card.
Shows exchange rates and fees transparently rather than only giving a conversion estimate.
Revolut — Best if you want budgeting tools too
Combines currency exchange, spending tracking, and card features.
Features and fees vary by plan and region.
Simple setup: Install XE for quick conversions + Wise or Revolut if you’ll be making lots of purchases abroad.
Public transit and navigation apps
Google Maps — Best all-around travel map
Transit directions, walking routes, saved places, and offline maps.
A reliable default for most destinations.
Citymapper — Best for major cities with complex transit
Excellent for metro/bus/tram combinations, real-time transit details, and step-by-step city navigation.
Coverage is city-dependent, so check your destination before relying on it.
— Good alternative for transit-focused trips
A practical travel phone setup
Google Maps — everyday navigation + offline maps
Citymapper — add it for big-city public transit trips
XE — quick currency checks
Wise or Revolut — international spending
Rome2Rio — planning longer journeys between places
Before leaving home, download offline maps for your destinations and open your currency app once while connected to Wi-Fi so cached information is available if your connection is poor.
Here are the top-rated apps for handling currency conversions and navigating complex public transit systems smoothly while traveling.
Best Currency Converter Apps
XE Currency Converter — The gold standard for travelers. It offers trusted live mid-market rates, supports over 130 currencies, and lets you track multiple currencies on a single screen. It also caches the last-updated rates so you can check numbers offline when you don't have active data.[](https://gotechsolutions.co/blog/best-currency-converter-apps/)
Citymapper — Unrivaled for urban transit if you are visiting a supported major global metropolis (like London, NYC, Paris, or Tokyo). It gives hyper-local, real-time step-by-step directions down to which subway car or exit platform will put you closest to your destination street.
Transit — Highly popular across North America and hundreds of international cities. It provides dead-accurate, crowd-sourced and real-time arrival times for buses and trains, featuring a brilliantly clear multi-modal timeline view that maps out every leg of your journey.
Google Maps — The reliable global fallback that works almost everywhere. While it can lack the niche hyper-precision of Citymapper in specific dense cities, its comprehensive public transit routing, offline map-download capabilities, and live schedule updates make it an essential baseline tool.
If you let me know which specific cities or countries you're visiting, I can give you tailored recommendations for any local transit apps or region-specific payment cards you might need.
For most travelers, a small set of apps covers nearly everything you need for currency conversion and public transit navigation.
💱 Currency conversion apps
Wise — Best if you also want to spend abroad or exchange money. It supports holding multiple currencies and shows exchange rates with transparent fees.
Best for: international trips, debit card spending, avoiding poor exchange rates.
XE — Best all-around rate checker. It’s widely used for live exchange rates, historical charts, and rate alerts; it can also keep recently updated rates available when offline.
Best for: quickly checking “How much is this in dollars/euros/etc.?”
Currency Converter Plus Live (and similar offline converters) — Useful if you expect unreliable internet access and mainly need quick price checks.
Best for: markets, taxis, small purchases without data.
🚇 Public transit and navigation apps
Google Maps — The best default choice for most destinations. It provides walking routes, transit directions, local search, and offline maps if you download areas before your trip.
Best for: almost any city, especially when you also need restaurants, hotels, and attractions.
Citymapper — Often better than general map apps in major cities because it focuses on transit details such as transfers, departure times, and route comparisons.
Best for: subway-heavy cities like London, Paris, New York, Tokyo, and other large metro areas (where supported).
A simple “install before you fly” setup
Google Maps — everyday navigation + offline maps
Citymapper — if your destination is a supported major city
XE — quick currency checks
Wise — if you’ll spend money internationally
Rome2Rio — for planning longer journeys between places
A good tip: download offline maps and refresh currency rates while you still have reliable Wi-Fi before leaving home.
If you’re traveling internationally, I’d keep it simple: one currency app + one transit app + Google Maps as a backup.
💱 Best currency apps
Wise — Best overall for travelers. Excellent for checking the mid-market exchange rate and useful if you also use Wise for spending or exchanging money.
XE Currency — Best dedicated currency converter. Simple, supports lots of currencies, and is particularly handy for quick “How much is this really?” calculations.
Google — Best for a quick conversion without installing anything. Just search something like “100 USD to EUR.”
Your banking app — Useful for checking the actual exchange rate/fee you'll face when paying or withdrawing, which can differ from the displayed market rate.
My pick:Wise + your bank's app. Use Wise to understand the fair rate; use your bank/card app to understand what you're actually being charged.
🚇 Best public-transit apps
Citymapper — Best for major cities and tourists. It specializes in public transportation and combines subway, bus, train, ferry, walking, bikes and rideshares. Its turn-by-turn transit guidance is especially good in complicated cities.
Transit — Best for live arrival information. Particularly useful when you're already at a stop and want to know what's actually arriving next.
Google Maps — Best all-around backup. Excellent for combining transit with walking directions, landmarks, restaurants and other places.
Moovit — Best alternative for broad international coverage, particularly when you're traveling somewhere Citymapper or Transit doesn't cover as well. Apple's current app recommendations also list alongside and for .

If you only want two apps:Wise + Citymapper for an urban international trip. Add Google Maps because it's so useful for walking and finding places.

When traveling internationally or exploring unfamiliar cities, having the right digital tools keeps your budget intact and prevents you from getting stranded. The top-rated apps for currency conversion and public transit navigation streamline your journey.
Citymapper — The undisputed king of urban transit in major metropolitan areas globally (covering dozens of major cities across North America, Europe, Asia, and Latin America). It combines every mode of transport—subways, buses, ferries, trains, and bikes—gives hyper-accurate real-time arrival times, and even tells you which specific train car or platform exit to use to get closest to your destination.
Google Maps — The most reliable all-rounder. It handles multi-leg public transit journeys seamlessly worldwide, shows live delays, and lets you download entire city areas for offline walking and transit reference.
Moovit — Known for having the broadest global reach, covering thousands of cities that larger apps sometimes miss. It provides crowdsourced crowd-level data, live schedules, and step-by-step transit alerts.
Local Official Apps — Always check if the city you are visiting has a dedicated municipal app (such as MTA in New York, City of Tokyo transit apps, or DB Navigator in Germany), as they frequently feature the fastest updates on sudden strikes, track changes, or local ticketing integration.
If you tell me which specific cities or countries you are planning to visit, I can give you tailored recommendations for local transit apps and regional payment methods.
If you’re traveling internationally, I’d use one currency app + one transit app, rather than trying to make a single app do everything.
💱 Currency
Wise — Best overall for travelers. It shows live mid-market exchange rates, supports 140+ currencies, and is especially useful if you also need to actually send or spend money abroad.
XE Currency — Best for rate tracking. Good for comparing lots of currencies, historical rates, charts, and exchange-rate alerts.
A dedicated offline converter — Worth having as a backup if you're visiting places with unreliable data. Download rates before leaving; don't assume live rates will work underground or without roaming.
My pick: Wise for most travelers; XE if you mainly want to monitor exchange rates.
🚇 Public transit
Citymapper — Best for major cities. Excellent for subway/bus/train combinations, walking transfers, disruptions, and step-by-step transit directions. It supports cities including Los Angeles, New York, London, Paris, Tokyo and many others.
Transit — Best for quick, real-time departures, particularly in North America. Its interface is designed around seeing nearby buses/trains and their arrival information quickly.
Google Maps — Best universal backup. It has extremely broad geographic coverage and combines transit with walking, driving and places. Dedicated apps can provide more detailed information in cities they specifically support.
🏆 My travel setup
For a typical international trip, I'd install:
Wise + Citymapper + Google Maps
Add XE if you care about exchange-rate tracking, and Moovit if you're visiting several countries or smaller cities.
One important tip: download maps/routes before leaving Wi-Fi. Offline maps can save you when you have no signal, but live transit arrival information generally still requires connectivity.
Here are the top-rated apps for handling currency conversions and mastering public transit systems seamlessly while traveling.
Best Currency Converter Apps
XE Currency Converter — The gold standard for global travel. It supports over 130 currencies, provides live mid-market rates, and allows you to track specific currency pairs. It also includes an offline mode that caches the last updated rates when you don't have active data. [](https://gotechsolutions.co/blog/best-currency-converter-apps/)
Wise — Beyond being a stellar platform for international money transfers and spending via multi-currency cards, the Wise App is invaluable for checking the exact, real mid-market exchange rate without hidden bank markups. [](https://gotechsolutions.co/blog/best-currency-converter-apps/)
Citymapper — Widely considered the ultimate app for urban transit. It covers major metropolitan areas globally, providing hyper-local real-time departures, multi-modal routing (subway, bus, ferry, walking, and bike share), and even platform/carriage guidance on which end of the train to board so you are closest to your exit.
Google Maps — The most reliable all-rounder. It works almost anywhere in the world, offering granular step-by-step public transit schedules, line tracking, and transfer instructions. Pro tip: download the Google Maps offline map for your destination city before venturing out to ensure your routing stays active without roaming data.
Moovit — Known as a massive global mobility-as-a-service app, Moovit fills the gaps in regions where other apps might be less precise. It excels at crowdsourced real-time arrival updates, service disruption alerts, and localized bus maps.
If you want to narrow this down, tell me:
Where are you traveling to?
Will you have continuous mobile data or do you need heavy offline functionality?
I can let you know if a specific local transit or regional payment app is required for that destination!
If you want a simple travel-app setup, I’d use one currency app + one transit app, rather than trying to make one app do everything.
💱 Currency
Wise — best overall for travelers. Good for checking exchange rates, holding multiple currencies, and spending abroad. A recent 2026 comparison also ranks it highly as an all-around travel-money app.
XE — best for quick currency conversions. Particularly useful when you just want to check “How much is €75 in dollars?” without dealing with travel banking.
My Currency Converter & Rates — best simple/offline option if your priority is rapid conversion rather than international money transfers.
My pick: Wise for actual travel spending; XE as a dedicated rate-checker.
🚇 Public transit
Citymapper — best for major cities. It specializes in buses, subways, trains, ferries, walking, bikes and other modes, with turn-by-turn transit directions and real-time comparisons.
Transit — best for real-time bus/subway tracking, especially in North American cities. Its strength is showing what's arriving now and guiding you through the trip.
Google Maps — best all-purpose fallback. It combines transit with walking, driving, places and general navigation, so it's the one I'd keep even if you install another transit app.
My travel stack
Wise + Citymapper + Google Maps is probably the best three-app combination for most international trips.
If you're traveling somewhere specific—e.g. Europe, Japan, Southeast Asia, or a particular city—tell me where, and I can narrow this down to the best apps for that destination.
Useful in many cities where you want dedicated public transport information.
Rome2Rio — Best for figuring out connections between cities
Helpful for questions like “Should I take a train, bus, ferry, or flight?”
Transit — A strong option in supported cities, with a simple interface for buses, trains, and real-time transit information.
Best for: travelers in North America and select international cities.

Best for: regional travel planning.
